Octagons

Above- a 1 minute video showing how to carve an octagon

Below- Step by step instruction

Place a 12″ square piece of ice on a plank of Foam

Multiply 12″ x .29 & you get 3.48″ (use 12″ because that is the width of the square)

Set your layout jig for 3.5″ & scribe the 4 lines.

Using a chainsaw, cut right on the outside edge of the lines
Using a pistol grip sander, smooth all of the flat surfaces
